As you can see, Guerrero was performing a rare feat. Among the hitters on this list, Cal Ripken was the most recent streak and that was nearly 12 years ago. All in all, it's not a great streak for Vlad's performance (although during Cal's walkless streak, he OPS'ed .964) but it was kind of fun to watch.

So going back to last season, Guerrero went 123 straight plate appearance without a walk before last night.
